Affine or Projective?

Today I hand clicked some 'base truth' correspondences so I can use them as a metric for image registration later on and play around with transformations. I wanted to make sure the affine transformation was a good estimate.

Subtracting Upper Left Camera from Upper Right Camera



Affine Transformation + Image Subtraction: SoSD = 658.7664


Projective Transformation + Image Subtraction: SoSD = 911.9480

*SoSD = Sum of Square Differences

These images are a lot better than what I'm expecting, but still, it looks like an affine 'motion model' will do fine. 

EDIT: Below are the raw images.

    Hi Tyler, can you show what the raw Upper Left Camera and Upper Right Camera images looked like?
